What is Bandwidth?

Bandwidth adds branded calling — the first move beyond closing self-service gaps.

Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.

What is Session?

Session pulls back from a funding crisis as community support revives development

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

Bandwidth vs Session: editorial side-by-side

B6.3

Bandwidth adds branded calling — the first move beyond closing self-service gaps.

◆ Current state

Most of Bandwidth's recent changelog reads as friction removal: Voice API debug logs surfaced in Voice Insights so customers stop opening tickets, self-service FOC date changes on port-in orders, MOS scores in the app, a longer delivery-receipt window. Identity Presentation breaks that pattern — it is a new product surface rather than a gap closed, putting brand name, logo and call reason on the recipient's handset with a pre-call authentication API to stop the display being spoofed.

◆ Where it's heading

Two tracks. Coverage keeps expanding country by country toward full PSTN replacement — Brazil, Mexico and South Korea landed together — which is the wholesale carrier business growing its footprint. The newer track is moving up the stack into call identity and trust, where the product is not minutes but whether the call gets answered. Identity Presentation arriving as a beta built on third-party providers suggests Bandwidth is assembling that layer rather than building it outright.

◆ Prediction

Expect Identity Presentation to move from beta to general availability with a defined pricing model, and the Identity Authentication API to be positioned alongside it as the anti-spoofing control. Country coverage announcements should continue on their steady cadence.

Session pulls back from a funding crisis as community support revives development

◆ Current state

Session's recent feed is dominated by survival, not shipping: a cofounder's personal appeal warning the project might not continue, followed by news that community donations, node operation, and awareness restored its runway and development will resume. Underneath sits real roadmap work — Session Protocol V2 (forward secrecy, post-quantum crypto) and the long-running Session Pro Beta.

◆ Where it's heading

The product spent recent months in existential mode and has now stabilized enough to resume development and keep critical infrastructure running. The technical direction — post-quantum cryptography and forward secrecy in Protocol V2, plus Pro Beta features — remains the substance, but momentum hinges on the donation-funded model that just rescued it.

◆ Prediction

Expect development to resume around Protocol V2 and the Session Pro Beta, with continued reliance on community funding; pace depends on whether the donation rebound holds.
